Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive metabolic disease caused by inactivating mutations in the CYP27A1 gene, encoding for sterol 21-hydroxylase, a mitochondrial enzyme, involved in bile acid synthesis. First reported by Bogaert in 1937, hundreds of cases have been described since,1 with an estimated prevalence of <5 per one million people worldwide. The enzyme deficiency leads to decreased bile acid synthesis with resultant excess production and tissue accumulation of cholestanol. This article is protected by copyright.
